3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
Critics of the concept dismiss Industry 4.0 as a marketing strategy. They suggest that although revolutionary changes are identifiable in distinct sectors, there is no systemic change so far. In addition, the pace of recognition of Industry 4.0 and policy transition varies across countries; the definition of Industry 4.0 is not harmonised.
Illustration of Industry 4.0, showing the four "industrial revolutions" with a brief English description. Industrial sociology, until recently a crucial research area within the field of sociology of work, examines "the direction and implications of trends in technological change, globalization, labour markets, work organization, managerial practices and employment relations" to "the extent to ...
Additive Manufacturing-Additive manufacturing is the "process of joining materials to make objects from 3D model data, usually layer upon layer." [ 12 ] Digital Additive manufacturing is highly automated which means less man hours and machine utilization, and therefore reduced cost. [ 13 ]
Digital modeling and fabrication is a design and production process that combines 3D modeling or computing-aided design (CAD) with additive and subtractive manufacturing. Additive manufacturing is also known as 3D printing, while subtractive manufacturing may also be referred to as machining, [1] and many other technologies can be exploited to ...
Stereolithography is a 3D-printing technique that uses photopolymerization to bind substrate that has been laid layer upon layer, creating a polymeric network. As opposed to fused-deposition modeling, where the extruded material hardens immediately to form layers, 4D printing is fundamentally based in stereolithography, where in most cases ultraviolet light is used to cure the layered ...
In 2022, engineers reported the development of swarms of autonomous 3D-printing drones for additive manufacturing and repair. [53] [54] In November 2022, researchers at the University of Maine Advanced Structures and Composites Center completed a 600 square feet (56 m 2) home composed of modular sections printed from wood byproducts.

Design for additive manufacturing (DfAM or DFAM) is design for manufacturability as applied to additive manufacturing (AM). It is a general type of design methods or tools whereby functional performance and/or other key product life-cycle considerations such as manufacturability, reliability, and cost can be optimized subjected to the capabilities of additive manufacturing technologies.
